Descriptores varietales de avena (Avena sp.) Cultivadas en México
Provedor de dados: 32
Autores: Jiménez Valle, Jesús Inocente.
Los estudios sobre descriptores varietales en avena son escasos en México. Por ello la importancia del presente trabajo para poder evaluar a los descriptores y ver cuales son aplicables sin que se modifiquen, cuáles se pueden considerar y cuáles podrían ser descartados, esto debido a que son fuertemente influenciados por el ambiente. El objetivo de este trabajo fue caracterizar las variedades de Avena sativa cultivadas en México, mediante el uso de descriptores varietales específicos. Para ello, se utilizaron 24 características descriptivas del SNICS para caracterizar las variedades de avena, así como las 8 que se proponen en este trabajo. Se establecieron en las localidades de Celaya, Gto, en el ciclo otoño-invierno 2006-2007 y en Texcoco Méx, en el ciclo...

Aspectos gerais das braquiárias e suas características na sub-região da Nhecolândia, Pantanal, MS.
Provedor de dados: 14
Autores: CRISPIM, S. M. A.; DOMINGOS BRANCO, O.
A escolha da gramínea forrageira, para formação de uma pastagem, deve ser bastante criteriosa, visando a maior produtividade de matéria seca e conteúdo de proteína bruta, com equilíbrio estacional e aceitabilidade pelos animais. A produção de forragem é um dos principais fatores capazes de afetar a produtividade de um sistema de pastejo. A principal atividade econômica do Pantanal está centrada na pecuária de corte e existe uma busca por forrageiras exóticas para o incremento da produtividade animal. Das gramíneas exóticas introduzidas no Pantanal as que vêm apresentando um maior destaque são as braquiárias, notadamente Brachiaria decumbens e B. humidicola. Este trabalho aborda as características gerais das seguintes espécies de braquiárias: B. decumbens,...

Morphological and mitochondrial DNA characteristics of two cultured species of cupped-oysters (Bivalvia : Ostreidae) in Hong Kong : towards a significant taxonomic name change
Provedor de dados: 5
Autores: Lam, Katherine; Morton, Brian; Boudry, Pierre; Heurtebise, Serge.
Cultured cupped-oysters species in Hong Kong have rarely been differentiated properly due to similarities in shell characters. This study attempted to characterize putative Crassostrea gigas and Crassostrea ariakensis by morphological and genetic means. Allometric ratios of shell height/length and depth/length were significantly different between the two species. Restriction fragment length polymorphism (RFLP) of a PCR amplified mitochondrial COI (cytochrome oxidase I) fragment was used to examine genetic differentiation between putative C. gigas from Hong Kong and previously studied populations of Crassostrea from Europe, Japan and Taiwan. The two Hong Kong species are not only morphologically, but also genetically different from each other in terms of...

Recent advances in EST sequencing in Crassostrea gigas: towards the sequencing of the Pacific oyster genome
Provedor de dados: 5
Autores: Boudry, Pierre; Huvet, Arnaud; Lapegue, Sylvie; Sauvage, Christopher; Tanguy, A.; Moraga, D.; Goostrey, A.; Prunet, P.; Boulo, Viviane; Gueguen, Y.; Moal, Jeanne; Fleury, Elodie; Samain, Jean-francois; Mathieu, M.; Favrel, P.
Rationale for EST and genome sequencing of the Pacific oyster: • its membership of the Lophotrochozoa, an little studied branch of the Eukaryotes, • its worldwide aquacultural importance (4.2 million metric tons, worth 3.5 billion US dollars), • its high fecundity, with concomitantly high DNA polymorphism, • its use as a biosensor of coastal pollution. In 2004, an international community of biologists, the Oyster Genome Consortium (OGC) led by D. Hedgecock (University of Southern California) and uniting 70 participants from 10 countries, first presented the Pacific oyster Crassostrea gigas as a genome-sequencing candidate to Joint Genome Institute (JGI, USA) (Hedgecock et al., 2005). Besides this project (that remains to be accepted), several EST...

TOWARD UNDERSTANDING HOUSEHOLD PREFERENCE FOR MILLET VARIETIES IN THE WEST AFRICAN SEMI-ARID TROPICS
Provedor de dados: 31
Autores: Ndjeunga,   Jupiter; Nelson,   Carl H.
In this study, we evaluate the preference of consumers in Niger for different tuwo or couscous characteristics using conjoint analysis.  Data were collected through a structured survey administered at 4 sites.  Preferences are estimated for three products (couscous, fermented tuwo and nonfermented tuwo) made from 5 pearl millet cutivars.  We provide relative valuation for different traits by type of product.  Results show that product taste, visual characteristics, and textural attributes are important.  The different valuation of characteristics across products and ethnic groups, however, suggests that signals regarding preferences may be very noisy.  Consequently, it might be difficult to design pearl millet improvement programs, or food processing...

Autores: Zhang,   Lijuan; Wang,   Jinxia; Huang,   Jikun; Rozelle,   Scott.
The overall goal of our paper is to better understand the development of groundwater markets in northern China. In particular, we focus on the factors that determine the development of groundwater markets in our attempt to explain their 'breadth' and 'depth.' Based on a survey of 24 randomly sampled villages and 50 randomly sampled tubewells in two provinces (Hebei and Henan Province) in 2001 and a field survey of 68 randomly sampled villages in 4 provinces (Hebei, Henan, Shanxi, and Shaanxi) of northern China in 2004, our results show that groundwater markets in northern China have emerged and are developing rapidly. Our results show that groundwater markets in northern China are informal and localized. The markets have developed in a way in which they...

An alternative for antibiotic se in poultry: probiotics
Provedor de dados: 89
Autores: Edens,FW.
Over the past 50 years, there has been increasing amounts of antibiotics used prophylactically and as growth promoters. Today, there is a consumer and governmental outcry to eliminate that practice from poultry and livestock production. Evidence has been accumulated to show that there is a link between risk of zoonotic disease and growth promoting antibiotic usage in livestock and poultry. Therefore, alternatives to the use of growth promoting antibiotics must be found to promote growth or production at or near the genetic potential of the modern day broiler, turkey, and egg producer. The use of probiotics has many potential benefits and include modified host metabolism, immuno-stimulation, anti-inflammatory reactions, exclusion and killing of pathogens in...

Epidemiological studies of short and long sleepers have not been conducted previously. We collected socioeconomic, psychological, and polysomnographic characteristics of 6501 parents (3252 men and 3249 women) of 4036 primary school children in Guangzhou city. The study data were collected in three phases. The overall prevalence of short (5 h or less) and long (10 h or more) sleep duration was 0.52 and 0.64%, respectively. Long sleepers had higher Eysenck Personality Questionnaire neuroticism scores [odds ratio (OR)=1.224, 95% confidence interval (CI)=1.047-1.409] and lower education levels (OR=0.740, 95%CI=0.631-0.849) than short sleepers. In the polysomnographic assessment, short, long, and normal sleepers (7-8 h) shared similar durations of Stage 3 sleep...

Characteristics of dr1790 disruptant and its functional analysis in Deinococcus radiodurans
Provedor de dados: 58
Autores: Cheng,Jianhui; Wang,Hu; Xu,Xin; Wang,Liangyan; Tian,Bing; Hua,Yuejin.
Deinococcus radiodurans (DR) is an extremophile that is well known for its resistance to radiation, oxidants and desiccation. The gene dr1790 of D. radiodurans was predicted to encode a yellow-related protein. The primary objective of the present study was to characterize the biological function of the DR1790 protein, which is a member of the ancient yellow/major royal jelly (MRJ) protein family, in prokaryotes. Fluorescence labeling demonstrated that the yellow-related protein encoded by dr1790 is a membrane protein. The deletion of the dr1790 gene decreased the cell growth rate and sensitivity to hydrogen peroxide and radiation and increased the membrane permeability of D. radiodurans. Transcript profiling by microarray and RT-PCR analyses of the dr1790...
